Discuss how we perceive colour.
✓
Answer
Perception of Colour: Colour is a crucial part of our visual experience. There are two main reasons why colour vision is of value to us.
Detection-Colour vision helps us to distinguish between an object and its background.
Discrimination-Colour vision makes it easy for us to make fine discrimination among objects.
Colour is determined by the wavelength or light waves which are the cause of all colours except its own. The object reflects light waves of its own colour while absorbing the rest. Brightness and darkness of an object or a coloured object is affected by its surrounding.
